LH900 Integrated Non-Ferrous Coating Thickness Gauge

The LH900 Non-Ferrous Coating Gauge: Now Consolidated Into the LZ990

The LH900 measured insulating coatings (paint, anodizing, plating) on aluminum, copper, brass, and other non-ferrous metal using a single integrated probe. It is no longer manufactured. Its measurement role is now part of the LZ990, a one-piece gauge that reads non-ferrous and ferrous substrates automatically, so a shop no longer needs a separate tool for each metal type.

What the LH900 Did

• Non-ferrous-only measurement: eddy current measurement of insulating coatings on aluminum, copper, brass, and other non-magnetic metal, with the aluminum (NFE-J) calibration substrate included.
• Integrated probe body: a single sealed handheld with a spring-loaded probe for curved and edged parts, no separate cable to manage.
• Field-ready range and accuracy: 0 to 1500 um (0 to 60 mils), accuracy of plus or minus 1 um below 50 um and plus or minus 2% above, on roughly 35 hours of battery life.

Why the LZ990 Replaces It

Your LH900 measured coatings on aluminum and other non-ferrous metal only. The LZ990 adds ferrous measurement in the same one-piece tool, detecting the substrate automatically with no mode to set. It also extends the range to 2000 um, adds onboard memory for roughly 1000 readings with statistics and lot functions, moves to 16 calibration channels, and adds USB and RS-232C output, none of which the LH900 had. Accuracy is unchanged: the LH900 already met the same specification.
